Burtscheid
Burtscheid (Latin language: Porcetum) is a town in western Germany, near Aachen. It was inhabited since ancient times by Celts and Romans, who were attracted by the presence of hot springs.
Burtscheid Abbey was founded here in 997 by emperor Otto III, with Gregor von Burtscheid as its first abbot. It was finished in 1016-1018.
